As you can read on www.delphiday.it the event has a day of in-depth seminars (Thursday, June 19th) and a conference day (Friday, June 20th). It's organized, as usual, in the city of Piacenza, Italy -- which incidentally is where I live ;-)
I'll be giving a keynote session on the status of Delphi, but you should attend for the many technical sections featuring international Delphi experts like Stefan Glienke, Yuriy Kotsarenko, Primoz Gabrijelcic, Michalis Kamburelis and a number of Italian Delphi experts and MVPs, starting with Paolo Rossi, who's also the organizer.
For anyone living in Italy or nearby, this is a great event not to miss.
